Repairing iPhone

Never attempt to repair or modify iPhone yourself. iPhone does not contain any user-serviceable parts, except for the SIM card and SIM tray. If iPhone has been submerged in water, punctured, or subjected to a severe fall, do not use it until you take it to an Apple Authorized Service Provider. For service information, choose iPhone Help from the Help menu in iTunes or go to www.apple.com/support/ iphone/service. The rechargeable battery in iPhone should be replaced only by an Apple Authorized Service Provider. For more information about batteries, go to www.apple. com/batteries.

Charging iPhone

To charge iPhone, only use the Apple Dock Connector to USB Cable with an Apple USB Power Adapter or a high-power USB port on another device that is compliant with the USB 2.0 or 1.1 standards, another Apple-branded product or accessory designed to work with iPhone, or a third-party accessory certified to use Apple’s “Works with iPhone” logo.

Read all safety instructions for any products and accessories before using with iPhone. Apple is not responsible for the operation of third-party accessories or their compliance with safety and regulatory standards.

When you use the Apple USB Power Adapter to charge iPhone, make sure that the power adapter is fully assembled before you plug it into a power outlet. Then insert the Apple USB Power Adapter firmly into the power outlet. Do not connect or disconnect the Apple USB Power Adapter with wet hands. Do not use any power adapter other than the Apple USB Power Adapter to charge iPhone.

The Apple USB Power Adapter may become warm during normal use. Always allow adequate ventilation around the Apple USB Power Adapter and use care when handling.

Unplug the Apple USB Power Adapter if any of the following conditions exist:

ÂThe power cord or plug has become frayed or damaged.

ÂThe adapter is exposed to rain, liquid, or excessive moisture.

ÂThe adapter case has become damaged.

ÂYou suspect the adapter needs service or repair.

ÂYou want to clean the adapter.

Avoiding Hearing Damage

Permanent hearing loss may occur if the receiver, earbuds, headphones, speakerphone, or earpieces are used at high volume. Set the volume to a safe level. You can adapt over time to a higher volume of sound that may sound normal but can be damaging to your hearing. If you experience ringing in your ears or muπed speech, stop listening and have your hearing checked. The louder the volume, the less time is required before your hearing could be a∂ected. Hearing experts suggest that to protect your hearing:

ÂLimit the amount of time you use the receiver, earbuds, headphones, speakerphone, or earpieces at high volume.

ÂAvoid turning up the volume to block out noisy surroundings.

ÂTurn the volume down if you can’t hear people speaking near you.

For information about how to set a maximum volume limit on iPhone, see the iPhone User’s Guide.
